My invention relates to a novel device for removing covers fromreceptacles especially receptacles having self-locking lids such as aresometimes used for the storage and shipg pin of frozen eggs.

'course, often results in One of the objects of my invention is toprovide a means for quickly and easily removing such covers withoutdamage to the cover or the receptacle.

Frozen e 'gs" are commonly packed in cans of thirty 30) pound capacity.One type of frozen egg can .is cylindrical and pro- ,vided with aself-locking lid, the lid or cover being in the form of a cap havingdownwardly extending sides flaring outwardly and .turned to provide abead adapted to being gripped or knocked which is integral with the lidor cover to permit removal thereof. It must be borne in mind that eggsafter packing in cans of this type are often subjected to lowertemperatures which results in the eggs expanding an bulging the sides ofthe can. This, of binding the lid and rendering removal diflicult.

My device which is novel in construction may be better understood byreference to the drawings in which Figure 1 is a plan view, Figure 2 isa side view, Figure 3 is an end view and Figure 4 is a view showing themanner of using the device. The device consists of shank 1, providedwith handle 2, strap 3 and hook i.

It is to be noted that strap or cross bar 3 is arched for greaterstrength, being flat at the ends 5 and 6, at which points contact ismade with the cover on the can at opposite sides thereof adjacent theskirt of the cover. It is to be noted that hook 4 is bent back towardthe handle in order to clear the head 7 which is integral with the skirt8 of the cover of the can 9.

In using the device, the operator grips it by the handle 2, places theends 5 and 6 of strap 3 in contact with the top of the can and insertsthe hook 4 under the bead 7. An upward pull on the handle 2 removes thecover in accordance with ordinary principles of physics.

It will be noted by reference to Figure 4 that the distance is less 1found in practice that if this increased more than half the the strap 3the cover.

distance be diameter of the become damaged and between the hook 4 andthan half the diameter of likely to The cover, the cover is bent inremoval.

peculiar construction of the hook, namely,

being so attached to the shank 1 as to form an acute angle on the handleside, ractically eliminates 'sli curs where the pping which it is toundochook is not so constructed due partly to the fact that the shank ofthe hook in ordinary 8 at 10 and partly to the fact that the cover usagecontacts with the upward force at the hook i is in the direction of theshank of'the hoolgthe components of this force being upward'and inward.The flat fulcrum portions of the arched crossbar or strap 3 by of thecover at opposite sides adjacent the skirt of the cover are d on thestrongest portion of the cover and consequently, the liability cover isreduced bearing against the thereof fulcrumed of injuring the to aminimum.

It is to be understood that changes may be made in the details of outdeparting from the s my invent1on with- 1r1t thereof as defined in theclaim which ollows.

I claim A device of the class described, comprisin a shank provided witha handle at one on a relatively long arcuate strap or cross bar securedto shank and extending at a rig the opposite end of the ht angle to theshank on opposite sides of the latter and having its ends provided withfiat fulcrum portions arranged to bear upon the upper face of the coverof a can at opposite sides thereof adjacent the skirt of the cover, and

a lifting hook ri gidly connected to the shank and extending at an acuteangle to the handle of the shank.
